Comparing the geographic distribution and location characteristics of HIV-seropositive and HIV-seronegative individuals with a diagnosis of cancer living in the southeast US

As HIV-seropositive individuals live longer, they are more likely to acquire conditions seen in the general population. Excluding AIDS-defining malignancies, HIV-seropositive individuals are more likely to develop cancer than individuals in the general population. In order to better inform future screening and prevention efforts in this population, we compared the geographic distribution and location characteristics of HIV-seropositive and HIV-seronegative cancer cases in South Carolina (SC). To do this we obtained linked HIV and cancer data from the SC enhanced HIV/AIDS Reporting System and Central Cancer Registry. Location-related information on SC residents (e.g., employment status, income levels, race of householder, and educational attainment) was obtained from the 2000 US Census. Hotspot analyses were used to analyze the geographic distribution of HIV-seropositive and HIV-seronegative cancer cases using the Getis-Ord Gi* statistic. Poisson regression analyses assessed if county demographic and geographic characteristics were associated with HIV-positive cancer case rates. (c) 2017 Elsevier Ltd. All rights reserved.
